Ventilation and outcomes following robotic-assisted abdominal surgery: an international, multicentre observational study

BackgroundInternational data on the epidemiology, ventilation practice, and outcomes in patients undergoing abdominal robotic-assisted surgery (RAS) are lacking. The aim of study was to assess incidence postoperative pulmonary complications (PPCs), describe ventilator management after RAS.MethodsThis an international, multicentre, prospective 34 centres nine countries. Patients ≥18 yr age RAS were enrolled between April 2017 March 2019. Assess Respiratory Risk Surgical Catalonia (ARISCAT) score used stratify for higher risk PPCs (≥26). primary outcome PPCs. Secondary endpoints included preoperative management.ResultsOf 1167 subjects screened, 905 included. Overall, 590 (65.2%) at increased Meanwhile, 172 (19%) sustained PPCs, which occurred more frequently 132 (22.4%) risk, compared with 40 (12.7%) lower (absolute difference: 12.2% [95% confidence intervals (CI), 6.8–17.6%]; P<0.001). Plateau driving pressures low but no ventilatory variables independently associated occurrence Development a longer hospital stay.ConclusionsOne five developed one or (chiefly unplanned oxygen requirement), stay.
